Abstract: A unique method and apparatus processes and validate Manchester-coded data transmitted on a communications channel and containing a synchronization word and a data word including a plurality of a data bits and coded according to a predetermined BCH error correcting code. Each data bits has a binary state determined by left half non-return-to zero (NRZ) bit sample and right half NRZ bit sample. The method for processing such data includes the steps of receiving a data work from the communications channel; checking the right half NRZ bit sample of the receive data word according to the predetermined error correcting code to detect the number of erroneous bit (810); error correcting the right half NRZ bit sample of the received data if the number of erroneous bits is less than a first predetermined number (814); comparing the left half NRZ bit sample to the error-correction right half NRZ bit samples of the received data word to determine the number of data bits that are in error (824); and discarding the receiver data word if it has more than a second predetermined number of data bits that are in error (830).The novel method may be used in processing data communications in any suitable system, such as, for example, data communications in cellular radio telephone systems.

Abstract: The inventive process includes reacting a mixture of olefin hydrocarbons and paraffin hydrocarbons within a reaction zone, having a lower portion, an upper portion, and a volume, in the presence of a sulfolane and hydrofluoric acid catalyst. This alkylation process includes introducing the hydrocarbon mixture into the lower portion of the reaction zone which contains the sulfolane and hydrofluoric acid catalyst and passing the resultant alkylate reaction effluent, which includes hydrocarbons and the catalyst, from the upper portion of the reaction zone to a settling zone. Within the settling zone, a phase separation occurs so as to produce a hydrocarbon phase and a catalyst phase. The catalyst phase is cooled to produce a cooled catalyst which is then utilized as the catalyst contained within the reaction zone.

The planar structure has an insulating substrate (23 to 25) and a set of electrodes composed of a working electrode (29), a counter electrode (30) and a reference electrode (31). A diffusion membrane (32) is deposited on the working electrode (29).      Connection means (26) are provided to connect the electrodes (29,30,31) to the measuring circuit (22).      According to the invention, the active conducting part of the working electrode (29), situated at the surface of the substrate (23) is entirely covered by the diffusion membrane (32) which overlaps this electrode (29) over its entire peripheral zone, whereas this membrane is entirely exposed so that, during the operation of the device (20) it is in contact with the fluid to be analysed over its entire surface.

Title: Hand-marked lottery selection slip scanning system and method
Inventor: MELLING ALAN
IPC: G06V30/224
Filed: 1996-02-29
Granted: 2007-05-29
Abstract: A system and method for capturing hand-marked cells from a lottery selection slip. The lottery slip includes a conventional play region of cells (labeled sequentially from 1 to 49, for example) for receiving indicia to be captured, after receiving indicia said play region of cells includes a plurality of occupied cells defined by marked cells and a plurality of non-occupied cells defined by unmarked cells. The lottery slip also includes row-identifier bar codes at opposite boundaries of the play region. The bar codes are electro-optically scannable and readable and are arranged in a plurality of ordered rows tiered along the transverse direction over the transverse distance of the play region. A scanner is used to generate scan lines that extend over the play region of cells occupied by the indicia and over each bar code and for decoding the row identifer data for each scan line as each line transverses the boundaries of the play region of cells, the occupied cells having different light reflectivity than the non-occupied cells. A decoder captures the identity and the location of the occupied cells and the non-occupied cells and stores the digitized signal. A ticket receipt is then issued representative of the numbers selected by the player. By using a bar code scanner to read both the row identifier codes and the actual hand-marked play region the need for precise positioning within traditional terminals is obviated.

Abstract: The plastic substrate portion of the part is formed by a first injection of plastic into a mold, so as to adhere to an overlying sheet of coverstock material. A portion of the coverstock is not initially adhered to the substrate. A second injection of plastic forms the undecorated portion of the part, and bonds to thesubstrate portion to form a unitary plastic panel. In the course of contacting the substrate portion, the plastic from the second injection folds and hides the non-adhered portion of the cover stock, thereby forming a neat, clean split line.

Abstract: A system is disclosed for making determinations related to the heat cycle in a cow. The system includes an electronic patch (30) attached to the cow. A transmitter module for transmitting heat mount data is contained in a pouch of the electronic patch (30). A removable and disposable battery (88) is also contained in the pouch for powering the transmittor module. The heat mount data from the transmitter module is sent to a repeater module (34) to maintain the quality of the transmitted heat mount data signal. The heat mount data is re-transmitted by the repeater module (34) to a central receiver module (38) which includes a memory for storing heat mount data. The heat mount data is downloaded to a computer (42) upon request using software that is also used to analyze the heat mount data. Analysis of the heat mount data results in determining a value that is useful in deciding on the optimal time to breed the cow.

Abstract: Un système de surveillance vidéo (10) comprend une caméra équipée d'un objectif oeil-de-poisson (20) offrant un champ de vision pratiquement hémisphérique. Ce système met en oeuvre des opérations équivalentes aux déplacements panoramiques ou en inclinaison et aux variations de focale d'une caméra conventionnelle. La caméra produit une image déformée d'oeil-de-poisson à cause des propriétés de l'objectif oeil-de-poisson (20). Le système (10) corrige cette distortion en faisant correspondre les pixels de l'image d'oeil-de-poisson avec des coordonnées produites lors du choix d'une zone particulière de l'image d'oeil-de-poisson à observer. Cette image d'oeil-de-poisson formée par la caméra est divisée en quatre parties différentes d'image (15, 16, 17, 18) transmises par quatre faisceaux de fibres optiques (35, 36, 37, 38).
